Enable GSM on US SPRINT CDMA Samsung Galaxy Tab S 10.5 LTE device

This device works in CDMA networks but I need it to work in GSM networks (GMS / HSDPA / LTE).

I'm outside US.

I have the MSL code and the device is already rooted (CF-Auto-Root), unlocked and debranded (idoneapps app). In addition with a custom recovery flashed (TWRP).

After a few weeks of trying different configurations (ServiceMode), programs (CDMA Tools, Qualcomm Tools, DFS, etc) and patches (editing the [login to view URL], etc) all, basically, taken from the XDA site, I'm still not getting connection to any (2G/3G/4G) of my 3 local carrires.

I have achieved that the 3 GSM SIM are being accepted (no more "Invalid SIM" message and I can see the network status icon: without signal)

I'm ready to restore the device to STOCK ROM state and buy the solution to get the device working in GSM networks.
